Definitions

  • the invention relates to a device for detacking leaf material, such as tobacco leaf or parts thereof, from a belt-shaped carrier or bobbin, which device is provided with a frame,
  • Such a device is used to remove a tobacco leaf or a part thereof in each case from the stretched belt part and to further transport it to a winding nest or the like.
  • a vacuum under the table so that the leaf is drawn fixedly onto the inside of the belt, but such air transport can bring about an excessive drying of the tobacco leaf, which is undesirable.
  • the invention has for its object to obviate the above stated drawback and provides thereto a device which is distinguished in that a straight guide edge is placed at a short distance, relative to the length thereof, from the front edge of the table to form a gap-like space, the winding-off reel is held in or close to a plane extending perpendicularly of the table and through the guide edge, and one of the guide rollers is arranged on the side of the guide edge remote from the winding-off reel.
  • the belt Due to the guide edge the belt is now bent sharply as a result of the placing of this guide roller, whereby the tobacco leaf is drawn loose of the belt part and is deposited on the same side of the belt part that is situated on the table, whereby the adhesion which can occur is eliminated.
  • the guide edge is preferably formed by the edge of a flexible plate which is preferably fixed to the frame with clearance.
  • the flexible plate can therefore tilt and bend slightly, this in the direction towards the bobbin, whereby the belt is bent simultaneously with the release of the bobbin.
  • the table is a wall part of a box connected to a vacuum source. Close to the front edge of the table the perforations are herein embodied as gap-like openings, which gaps extend in the direction of movement of the belt.
  • FIG. 1 shows a perspective view of the device according to the invention
  • FIG. 2 shows on an enlarged scale a perspective view corresponding with FIG. 1 of a detail of the device.
  • Designated with the numeral 1 is the frame of the device, which frame can be embodied in random manner within the scope of the invention, wherein it can also form part of a larger device, for example a cigar winding machine.
  • a standing plate 1 to the forward side of which is fixed a table 2 such that the top surface thereof extends horizontally or almost horizontally.
  • a winding-off reel 3 On the top side of the table 2 is arranged a winding-off reel 3, the shaft of which is fixed to the outer end of a balance arm 4.
  • the balance arm 4 is pivotable up and down around a pin 5 in the direction of the arrow Pl wherein a counter-weight 6 is arranged on the other end of the balance arm 4 to compensate for the weight of the bobbin B arranged on the winding-off reel 3.
  • a tiltable and/or flexible plate 7 Arranged on the front edge 26 of the table 2 is a tiltable and/or flexible plate 7 whereof the guide edge 8 is situated at a short distance from the front edge 26, so that a gap-like space is formed between plate 7 and table 2.
  • the flexible plate 7 is fixedly held with clearance on the side remote from the guide edge in a Unshaped strip 9 which is attached with screw means 10 to a fixed plate 15 which is fixedly welded or attached in other manner to the frame 1.
  • the plate 7 with the guide edge 8 can thereby move up and down to a limited extent in the vertical plane.
  • a box 11 Arranged on the bottom side of the table 2 is a box 11 which is connected via the stump 12 to a vacuum source (not shown), wherein the table 2 is provided in the manner shown in FIG. 2 with slots 13 and 14 respectively.
  • the slots 13 extend perpendicularly of the front edge 26 in the direction of the movement of the belt for guiding over the table, according to the arrow P2 in FIG. 1.
  • transverse slots 14 Arranged therebehind are transverse slots 14 which can also be replaced by circular perforations.
  • a fixed guide roller 16 On the underside of the flexible plate 7 is arranged ranged a fixed guide roller 16 the rotation shaft 17 of which is situated at just below the clamping strip 9, that is, close to the fixedly clamped side of the flexible plate 7.
  • the rotation shaft 17 is again fixed to the frame plate 1.
  • a second guide roller 18 Arranged behind the table 2 is a second guide roller 18, the rotation shaft of which is likewise fixed to the frame plate 1.
  • a pair of drive rollers 19 is arranged at a distance below the box 11 wherein the large roller thereof is driven by a motor 21 in the direction of the arrow P3, wherein the motor is designated schematically in FIG. 1, but is supported on the frame 1.
  • a winding-up reel 20 is placed in the top left-hand corner of the frame plate 1 to take up the emptied bobbin winding.
  • the winding-up reel 20 is driven in the direction of the arrow P4 by the motor 21 via a chain with slip coupling 27, 28 to enable winding of the belt.
  • winding-off reel 3 is braked in a manner not further shown, in order to maintain sufficient belt tension in the belt during the repeated stepwise forward movement by means of the pair of drive rollers 19.
  • the belt is then trained manually along the guide edge 8, the guide rollers 16, 18, 19 such that the belt can further be wound onto the winding-up reel 20.
  • the belt can be pulled stepwise from the bobbin B.
  • the tobacco leaf material T fixedly clamped on the windings of the bobbin are disengaged from the belt part and deposited through the small gap width directly onto the belt part which is situated at the beginning of the table 2.
  • This transfer is further improved by the vacuum in the box 11 which ensures that air is drawn in via the perforation slots 13 and 14 respectively. This transfer is improved still further due to the lengthwise slots 13.
  • the sharp bending of the belt part is furthered by the balance arm 4, which ensures that under a light pressure the bobbin B rests respectively on the front edge 26 of the table and the guide edge 8 of the plate 7.
  • the plate 7 will be tilted or bent slightly in upward sense, this against the underside of the bobbin B, which ensures that the leaf material, in particular tobacco leaf material, is drawn loose immediately and transferred onto the belt part at the beginning of the table.
  • the weight that must be compensated can be adjusted simply by moving the position of the counter-weight 6 relative to the balance arm 4 until the desired pressure of the bobbin is reached close to the gap at the beginning of the table 2.
  • the invention is not limited to the above described embodiment.
  • the roller 1 does not for instance have to lie close beneath the fixing strip 9 and flexible plate 7 respectively but can also occupy another position depending on the desired bending of the bobbin material.
  • the surface of the table 2 have to extend in horizontal sense but may also occupy a sloping position depending on the construction of the desired detacking device for detacking the leaf parts T, which is assumed to be known and is therefore not reproduced in the figure.
  • the plate 7 can also be fixedly clamped and effect an up and downward movement of front edge 8 through its own flexibility.
  • the driving of the belt of the winding B can also take place in a manner other than that described and shown.
